The Application of Tribological Tests to Study the Wear Behavior of Asphalt Cutter Teeth: An Experimental Investigation Using Baroid Tribometer

In this paper, the authors present results obtained within a complex experimental program that focuses on determining tribological characteristics of active part (tungsten carbide tooth tip) cutter teeth asphalt milling equipment. The experiments are performedunderdifferent testing conditions (in dry environment and in water) to highlight need use water, when coating, with purpose reduce wear teeth. show water contributes substantial reduction rate (more than eight times) area tooth. proposed test method—testing Baroid tribometer—is intended evaluate materials using parallelepiped-shaped samples. work performed tests samples represent having real shape (so not samples). demonstrate method can be used good parts.
